You receive a US$1 return per contract if your prediction is correct and nothing if it is incorrect. The market resolves when the party that controls the U.S. Senate is determined in 2026. The official resolution sources are the agencies listed in Rule 14.65(c) in the CDNA Rulebook, which can be found here [https://www.nadex.com/rules/]. Liquidity may be low after the election results start coming in. Trading is temporarily paused during scheduled maintenance periods.
